FRANK .T. SENG, OF CHICAGO, ILLINOIS, ASSIGN OR TO TI-IE SENG COMPANY, ACORPORATION OF ILLINOIS.

EXTE NSION -TAB LE To all whom it may concern:

Be it known that I, FRANK J SENG, a citizen of the United States,residing at Chicago, in the county of Oook and State of Illinois, haveinvented certain Improvements in Extension-Tables, of which thefollowing is a specification. l

This invention is an improvement in eX- tension tables, and relates moreespecially to the class of pedestal extension tables, in which thepedestal is divided or formed in two sections which support theeXtensible sections of the top and are adapted to come together or meetwhen the table is closed and thereby form a central pedestal or pillar.In this type of table it is a common fault for the pedestal sections tosag or spread apart at their lower ends, after being used to some eX-tent, resulting in a widening crevice or crack between said sections andextending to the lower ends thereof. This unsightly crevice or crackwill gradually widen as the table is used, and therefore numerousdevices have been provided for adjusting the pedestal sections on alinewith each other so that they will properly come together and form aclose joint throughout the length of the pedestal or pillar.

The principal objects of my invention, therefore, are to provide `adevice for adjusting the pedestal sections of an extension table that issimple in construction and therefore cheap to manufacture, may be easilyapplied to any of the ordinary forms of pedestal extension tables, andwhen applied can be easily and conveniently operated to secure anydegree of adjustment and thereby insure a proper joint between saidsections.

The invention consists in the construction, combination and arrangementof parts hereinafter particularly described and specifically set forthin the appended claims.

In the drawings accompanying this specification: Figure 1 is a sideelevation, partly in section, showing the application of the invention,and illustrating only those parts to which the devices are adapted to beapplied. Fig. 2 is a sectional view on the line 2 2 of Fig. l. Fig. 3 isa sectional view on the line 3 3 of Fig. l. Fig. 4 is a plan view of thewedge employed. *ig 5 is a side elevation of said wedge.

Like numerals of reference indicate like parts in all the figures of thedrawings.

Specification of Letters Patent.

Application filed March 2, 1907.

Serial No. 360,160.

Referring to said drawings, l 1 designate the two sections of thepedestal, 2 2 the secl are secured to the pedestal sections, and 4 4 thebridge-blocks by which the top sectionsA are secured to the brid'e-pieces. Each movable section of the tab e therefore comprises theusual number of parts, to wit: the pedestal section and its brid eieceand block, and a top section or tablcl eaf which is secured to saidblock. I/Vith the exception of the bridge-block these parts are of theordinary construction. stance I prefer to make the bridge-block ofmetal, but as will be obvious hereinafter the customary wooden blockcould be employed. The bridge-block herein shown is made of sheet metalbent into substantially Z-shape in cross-section so as to provide theattaching flanges 5 at its opposite ed es. These sheet metalbridge-blocks or ang e plates not only possess the advantage of Ibeinglighter than In the present inthe usual wooden blocks, but also providea harder engaging surface for the wedges hereinafter referred to. Fourof these bridgeblocks or angle plates are employed, as is usual, two foreach section of the table, and

as a set of my improved adjusting devices is applied to eachbridge-block or angle plate a description of one will, of course, answerfor all, the same reference numerals being used in each instance.

, In attachin the bridge block` or angle plate it is rigid y secured byits upper flange to the underside of the table top with woodscrews, asindicated in Figs. 2 and 8, and by its lower or base-flange is connectedto the bridge-piece 3 through the medium of bolts and winged nuts 6 and7, respectively, two of which are employed and located near the oppositeends of said base-ange. This latter connection permits of a separationof the parts 3 and 4 at either or both ends by manipulating the wingednuts and in conjunction with a wedge 7 inserted between said parts atone end thereof so that the vertical disposition of the pedestal sectioncan be use.

move the lower end of the pedestal section inward or towards thecompanion pedestal section.

In the operation of the wedge the nut on the bolt at the outer end ofthe parts 3 and 4 is first loosened slightly and the wedge is thendriven in until it binds tightly and will of course depress the outerend of the bridgepiece 3 and move the lower end of the pedestal sectioninward, and if this adjustment is not suhcient the operation is repeateduntil the desired adjustment is had. The binding of the wedge betweenthe parts will hold the adjustment by irictional contact, and of courseadditional frictional engagement may be secured by roughening thesurfaces of the wedge. In adjusting the parts by driving in the wedgethe bolt-head at the inner end of said Vparts become the fulcrum for theflange 5 of the bridge-block or angle-plate, and of course the drivingof the wedge tends to separate the parts at the inner ends thereof.Therefore, by adjusting the nut on said fulcrum-bolt it is possible alsoto adjust the upper end of either pedestal section to'bring it on a linewith the other or companion section. It will be seen, therefore, thatthe devices described provide for adjustin the pedestal sections bothvertically and aterally, to thereby produce a close and even jointbetween said sections, and so that the ornamentations or beads on onewill aline with those on the other.

Though an ordinary plain wedge may be employed I prefer to use one ofthe construction herein shown and described, as it is lighter and willkeep in proper alinement with the base-flange while being driven and inFor these purposes the wedge comprises a longitudinally slotted plateJforming the body and provided at its opposite longitudinal edges withflanges 9 the upper edges of which are inclined as sliown, and at thesmaller end of the wedge, at opposite sides thereof, are formed ears l0which are adapted to embrace the edges of the flange 5 and form guidesfor the wedge. The longitudinal slot at the center of the wedge is forthe passage therethrough oi' the bolt 6, and said bolt therefore servesas an additional means for holding the wedge and keeping it inalinement.

Having described my invention, what I claim as new and desire to secureby Letters- Patent, is

1. In a pedestal extension table, the combination with opposite tablesections connected to move to and from each other, and

having retaining ears at its longitudinal edges adapted to bear on eachside of said connecting piece.

2. In a pedestal extension table, the combination with opposite tablesections connected to move to and from each other, and each comprising atop section, a pedestal section, and a connecting piece attached to andlying between the same, of bolts securing said connecting piece to oneof said'sections and located near the opposite ends of said piece, and awedge interposed between said connecting piece and said latter sectionand having a longitudinal slot through which passes one of the retainingbolts, and retaining ears at the smaller end of said wedge adapted tobear on each side of said connecting piece.

3. In a pedestal extension table, the combination with opposite tablesections connected to move to and fronti each other and each comprisinga top section, a pedestal section, and a connecting piece attached toand lying between the same, of bolts securing said connecting piece toone of said sections and located near the opposite ends of said piece,and a wedge interposed between said connecting piece and said lattersection and comprising a plate having a longitudinal slot to receive oneof the retaining bolts, inclined walls at the opposite longitudinaledges of the plate, and retaining ears at the smaller4 end of the wedgeadapted to Abear on each side of said connecting piece.
